Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee! are headed to Nintendo Switch this holiday season, giving new and old players alike the opportunity to visit an HD Kanto. Although these remakes are primarily sticking with Pokémon from the original games, they are spicing things up a bit with some modern mechanics, including Mega Evolution. The Pokémon Company has just released a new trailer, and this time it focuses on Mega Kangaskhan and Mega Gyarados.
